CURRIERS CLOSE
CHARTER AVENUE
COVENTRY CV4 8AW
TELEPHONE: PRODUCT INFORMATION: 024 7642 1222
FAX: 024 7642 1192
CHEMICAL NAME:
PRODUCT: CUBIC BORON NITRIDE WAFERING BLADE
PRODUCT NUMBERS: Various
IMPORTANT NOTICE Cubic boron nitride abrasives are inert products, which do not create any risk when handled
or stored. When used on cutting machines they require specific measures to protect operators. During cutting operations 90%
or more of the particulate of dust come from the material being cut and, for wet cutting, from aerosols generated by the cutting
fluid. Specific attention must therefore be given to the nature of the part and of the fluid and the appropriate protection devices
must be installed.
2. COMPOSITION / INFORMATION ON INGREDIENTS
CHEMICAL NATURE: cubic boron nitride with resin, metal or vitrified bonds
INGREDIENT (S): CAS NUMBER: % OSHA LIMIT ACGIH TLV CARCINOGEN
10 mg/m 3 10 mg/m 3
Cubic Boron Nitride 10043-11-5 1-5 N
3. HAZARDS IDENTIFICATION
If handled and used for abrasive cutting purposes as indicated, the substance presents no critical hazards to man.
EC Directive No 88/379.
4. FIRST AID MEASURES
GENERAL INFORMATION: In all cases of doubt, or when symptoms persist, seek medical attention.
INHALATION: In dry applications, abrasive products may generate nuisance dust. There may therefore be a
requirement for local exhaust ventilation and/or respiratory protection. Exposure to this dust should be
adequately controlled and personal exposure kept below 10 mg m-3 8 hour TWA total inhalable dust,
or 5 mg m -3 8-hour TWA respirable dust. In addition, the airborne concentration of the material should
be considered.
SKIN: Should irritation occur, seek medical attention.
EYE: Dust may cause irritation. Abrasive grit in the eyes may cause damage and eye protection is required.
In case of grit in the eyes, seek medical/ophthalmic advice.
INGESTION: NA.
5. FIRE FIGHTING MEASURES
EXTINGUISHING MEDIA: Use any standard extinguishing media.
UNSUITABLE EXTINGUISHING MEDIA:
FIRE FIGHTING PROTECTIVE EQUIPMENT: A self-contained breathing apparatus and suita ble protective clothing
should be worn in fire conditions.
